Final Answer:
A rectangular room is 6 m long and 4.5 m wide. The floor will be tiled with square tiles of sides 15 cm then you will need 1200 tiles.
Step-by-step explanation:
To find the number of tiles needed, first, calculate the area of the room:
Area = Length × Width
Area = 6 m × 4.5 m = 27 m²
Convert the area to square centimeters (1 m² = 10,000 cm²):
Area = 27 m² × 10,000 cm²/m² = 270,000 cm²
Now, find the area of one tile:
Tile Area = Side × Side
Tile Area = 15 cm × 15 cm = 225 cm²
Finally, divide the total area of the room by the area of one tile to get the number of tiles needed:
Number of Tiles = Total Area ÷ Tile Area
Number of Tiles = 270,000 cm² ÷ 225 cm²/tile = 1,200 tiles
Therefore, you will need 1,200 tiles.
